Laughing gas is officially banned in Ibiza – with anyone caught inhaling it in public facing a fine of up to £1,400.
At present officials can only take action if they catch someone selling balloons in the street, as British portal The Sun reports.
The new measures to bring in fines ranging from €750 (£647) to €1,500 (£1,374) will be voted on at a council meeting next Wednesday.
Brits are reported to be the main buyers of laughing gas, which is banned in the UK for human consumption, and are often seen buying it from beach sellers.
The drug has been linked to eight deaths in Britain in the last year.
A spokesperson for San Antonio Council said: “The government team in San Antonio will propose a modification to an existing by-law governing civil coexistence which will ban the consumption of nitrous oxide in public. Under the current rules, local police can only act against those people they catch selling the substance in the street.“
Holidaymakers caught breaking the rules will face hefty fines of up to €3,000 (£2,700).
